I can help with your app ive done a wordpress integration into an app before.

Here is a link: https://bitcointalk.org/index.php?topic=455528.msg5021008#msg5021008

look at the website eddiecreek.ca and the link to the app in the app store is: https://itunes.apple.com/us/app/eddie-creek/id783737757?mt=8


I can adapt this to anything your looking for and turn out a product faster since i have the base. Fil me in on the app and existing wordpress and we can discuss this further
